TURNTABLE FOR TALKING MACHINES.

Application filed March 13, 1918. Serial lib/222,139.:

T 0 all whom it may concern.

Be it known that I, ANT ONY VAssnLLI,

dent of the city ofNewark, county'of Essex, and State of New Jersey,have invented a certain new and useful Turntable for Talk ing Machines, of which the following isa jg specification. I

My invention relates to means for securing a pad to turn-tables of disc talking machines and theproduction of means so thatv such pad will not become disarranged in ;use and to prevent the unraveling of the ing pad or cushion means on which the record disc rests, The frictional engagement of the record disc with the felt pad is depended on to prevent relative rotation of the record disc and turn-table when theformer is engaged by the stylus of the reprod ucer.

The felt disc or pad has, been found unsatisfactory for several reasons, the principal -easonbeing that when the pad has A i;- been used forsome time, its upper surface becomessmooth, shiny andslippery, and the engagement of therecord groove in the moving disc with the stationary reproducer stylusnvill cause the record disc to slip and permit the turn-tableto. rotate at a higher speed. than that o fthe record disc.

, The employment of apad composed of velvet or other pile fabric has been proposed, but the material was found objec- 5 tionable for the reason that ardisc cut of the woofris shortest.

textile fabric will present very short threads at four points on its periphery; the warp threads being shortest where'the woof is longest, and the warp being longest where The fabric will un ravel at these four points, and the short threads will become disengaged from the pad. Such threads are likely to get on the surface of the record disc and into the record groove, and mar the reproduction. The ends of the long threads which remaln, W111 project beyond the body of the'pad, will curl or kink, land formdgnots or bunches which lying under the record disc and be- 1 tween it and the turntable,iwill prevent the discfrom lying flat'on-thesame, The of the pad will be raggedefringed and' un tidy in appearance. The back of -,a pile fabric such as plushorvelvetgbeing of hard twisted yarn will be-smooth and permit the, pad to slip relatively-to the turn-table. 1

A pile fabric makes an ideal and more effective covering for a turn-table than afelt. pad as the ends of the cutpile threads form an effective friction surface. The pilemust. be worn-entirely oif before the top surface becomes hard and shiny and; thereby allow the record disc to slip. 1 r r The objects of my invention are to prevent the unraveling of the edges'of a; disc of textile fabric, suchas, velvet, plush or the like, to provide means for securing-a pad to a-turn-table to prevent relative movement of the pad and turn-table, to provide means for protecting the covering orpad of a turn-table, to provide a pad whichwill not become disarranged, and improve the appearance of a turn-table, provided with fabric covering. i

The invention contemplates the provision of means for supporting and retaining the pad injits proper position on the turn-table to protect the fabric from injury, and to effectively prevent unraveling of the fabric.

A further object of the invention isthe provision of means of the character described, which are extremely simple in con-Y panying drawings considered together or separately.

trating the invention, are shown: in theac companyingjdrawingsi I 7 I The invention will, befirstfdesdibed in connection with the accompanying drawings, wherein similar reference characters are used to designate correspondingparts throughout the several views, and then more specifically defined. and indicated in the appended claims.

In the. drawings,

Fig. l is a topplan view of a talking machine turn-table provided with my invention;

Fig. 2 is a sectional view on an enlarged scale, said section being taken on the line 22 of Fig. l;

Fig. 3 is a detail View of a modification; and

" Figs. 4 and 5 are detail sectional views of additional modifications.

In the drawings, 1 designates a talking machine turn-table of any approved type. The turn-table has a central boss or hub having an orifice 2 forthe passage or reception of the upper end of the turn-table spindle, The periphery of the turntable is thickened on its lower face to form a downwardly extending flange'3. The upper surface of the turn-table is removed to form an annular recess 4 adjacent to the periphery thereof'for the purpose hereinafter described. A circular disc pad 5 of velvet, plush or other pile fabric is placed in position on the upper surface of the turntable. The pad 4 is'of such a diameter as to permit of the properadjustment of the securing and retaining means as hereinafter described.

A metal ring 6 having acylindrical flange 7 is placed in position over the edge of the turn-table 1, the ring 6 depressing the outer edge of the disc pad 5 into the recess l. The flange 7 is secured to the periphery of V the. turn-table by soldering or in any suitable manner so as to retain the ring in position. The depth of the recess 4 is such that the ring 6. will lie belowthe level of the top of the disc pad 5, and thereby in no manner interfere with the proper holding of the disc record by thefpad.

The center of the pad 5 is provided with a perforation 8 .for the passage of the tip of the turn-table spindle, and in order to prevent unraveling ofjthe textile fabric at this edge of the said perforation, there is provided a metal or other binding in the form of an eyelet 9 having an opening corresponding and registering with the orifice 2 f the turn-table shaft and the perforation 8 of the pad 5. Such eyelet has an annular groove on its periphery into which groove the pad is inserted toprevent unraveling.

In the modification shown in Fig. 3, a flange 11 is formed as an integral part of and over the uppersurface of the turn-table surrounding the orifice 2, and this flange is; turned down over the edgeof the opening 8 in the center of the pad, thereby forming an annular recess or groove between the flange and the surface of the turn-table into which is set the edge of'the fabric surround ing the opening 8 in the pad 5 to prevent unraveling of its edge. r

The modification shown in Fig. 4 illustrates a construction in which the outer edge of the recess it is, formed by an upstanding bead or projection l on the periphery of the turn-table, The retaining ring 16 engages the topof the bead or projection and the edge of the pad 5 while the flange of the ring may be soldered in place as'in Fig. 2 or it may be forced in place and held by friction.

Fig. 5 shows a modification in which the turn-table of Fig. 4 is employed and the flange of the ring 17 is turned under the flange 3 of the turn-table l as at 18.

In both these forms, it will be observed that the ring 16 engages the bead or projection l and prevents the ring from being pressed too hard or forcibly upon the edge of the pad, the bead being of such width and height to permit the ring to overhang and engage the edge of thepad to hold it in place and protect it against raveling.

By my invention the disc pad is secured in place on the top of the turn-table, the outer and inner edges are bound to preventunraveling, the binding and securing elements may be highly polished and plated or colored, as desired, so asto greatly improve the appearance of the apparatus. 7

lVhen the pad as above applied to the turntable becomes worn out and does not effectively serve its purpose of frictionally engaging the record, it may readily be removed by simply working or pulling its outer peripheraledge from, beneath the overhanging flange of the retainin ring 16 or 17 and the pad lifted from the turntable with its attached reinforcing eyelet, as in Fig. 2, or in the case of the reinforce for thespindle opening made integral with the turn table, as'in Fig. 3, the edge of the pad at thev spindle opening may be drawn or pulled from the groove formed by the flange. 11, and the pad lifted from the table, and

when thus removed, theturntable may be supplied with a new pad, and in case the pad is of the form shown'in Fig. 2, with the attached reinforcing eyelet at the spindle opening, it' is simply necessary to slip the reinforced spindle opening over the spindle I projection l of the turntable, upon which the flange of the ring 17 rests, affording sufficient space between the groove 4 and said flange to receive the edge of the pad.

In the construction shown in Fig. 3, where the spindle opening of the pad is not provided with an attached reinforcing eyelet, the raw edge of the pad at the spindle opening may readily be' forced into the groove formed by the overhanging flange 11 at the spindle openin in the turntable, and said raw edge effectively prevented from becomin unraveled.

I rom the foregoing it is obvious that a new pad may be readily inserted and the old one removed by using fastening means which hold the ring by spring pressure in frictional engagement with the periphery of the turn-table in place of using solder to retain said ring in position.

The rings may be constructed of any desired material, metal, rubber, wood, textile material or the like.

I desire to have it understood that my in vention may be carried out by the use of pads made of materials other than pile fabrics such as velvet or plush. The ordinary felt or any other suitable material may be employed.

The operation will be obvious from the above description and accompanying drawmgs.

In accordance with the provisions of the patent statute, I have described the principle of my invention together with the apparatus which I now consider to represent the best embodiment thereof, but I desire it understood'that my invention is not confined to the particular form of apparatus herein shown and described, the same being merely illustrative, and that the invention can be carried out in other ways without departing from the spirit of my invention, and, therefore, I claim broadly the right to employ all equivalent instrumentalities coming within the scope of the appended claims, and by means of which objects of my invention are attained, and the new results accomplished, as herein set forth, as it is obvious that the particular embodiments herein shown and described are only some of many that can be employed to attain these objects and accomplish these results.

Having now described my invention, what I claim and desire to secure by Letters Patent is as follows:

1. A turntable for talking machines, having a bead or projection rising from the periphery thereof, and an annular recess in the top of the turntable adjacent to said bead or projection, an annular flange overhanging said recess, and a pad fitted upon said turntable with its peripheral edge extending into said recess, said flange engaging the edge of.

the pad to hold and protect the same in said recess. 1

2. A turntable for talking machines, having a bead or projection rising from the periphery thereof, and an annular recess in the top of the turntable adjacent to said head or projection, a pad fitted upon said turntable with its peripheral edge extending into,

said recess, and a ring fitted to the periphery of the turntable and having a flange resting upon said bead or projection and overhanging said recess and engaging the edge of the pad to hold and protect the same in said recess.

This specification signed and witnessed this 12th day of March, 1918.
